POWER-TRANSMISSION MECHANISM.

SPECIFICATION forming part of Letters .E'atent No. 759,222, dated May10, 1904.

Application filed February 26, 1900. Renewed December 13, 1902. SerialNo. 135,165. (No model.)

To all whom it "may concern:

Be it known that I, Bron J. ARNOLD, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Power-TransmissionMechanism, (Case No. 3,) of which the following is-a full, clear,concise, and exact description, referen'ce being had to the accompanyingdrawings, forming a part of this specification.

My invention relates to power-transmission mechanism, and moreparticularly to that class of power-transmission mechanism employed foroperating vehicles, although the invention has other application, andhas for its object the improvement in construction of such mechanismwhereby functions hereinafter more particularly set forth may beperformed, and the invention in all of its details will be hereinafterfully described, and set forth in the appended claims.

By means of my invention I am enabled to store the energy that is wastedin braking the wheels of the vehicle and use the same to aid thevehicle-motor in propelling the vehicle as, for example, in startingvehicles from a state of rest. By means of my invention I am alsoenabled to use stored energy for aiding the vehicle-motor in climbinggrades and to sufficiently retard the travel of the vehicle indescending grades. Bymeans of the apparatus of my invention I make useof that power otherwise wasted in checking and stopping the travel ofvehicles.

.ln the preferred embodiment of my invention I employ pneumatic motormechanism, which may either act as a driving or a driven motor, theconstruction being preferably such that the pneumatic motor mechanismwhen being driven will pump air into a confined space, whereby the saidmechanism will act as a brake, provision being made to prevent air orother fluid from being stored under too great a pressure, which wouldcause thevehiclewheels to skid. For this purpose] preferably employpop-valve mechanism which is capable of permitting the air to escapewhen under excessive pressure. The apparatus ofmy invention thus affordsa flexible coupling between the vehicle-motor and the wheels driventhereby, this flexible connection being such,

as to operate either as a driving dutch-motor to start the vehicle inmotion or as a driven retarder to act as a brake.

My invention in its preferred embodiment relates to electric-tractionsystems in which single-phase or synchronous or single-phasealternating-current motors may be employed to effect the travel of thevehicle.-

As is well understood by those skilled in the art, difficulty hasheretofore been expert enced in employing the most efficient singlephase alternating-current motors for the nropulsion of electricvehicles, a great diiiicuit residing in means for stopping and startingthe motor. The most eflicient motors for the purpose are those whichwill operate with great est efficiency at synchronism or nearsynchronism, and those motors technicaliy termed speed of the vehicleout of correspondence with Y the speed of the motor by the employment ofvariable-speed connection between the vehicle-motor and the vehiclerunning-gear.

In accordance with my present invention 1 I employ a motor that ispreferably constantly operated at a uniform rate of speed irrespcw tiveof the speed of the vehicle, and in the preferred embodiment of theinvention as employed in electric-traction systems it employ asynchronous motor or a single-phase fag-motor preferably operated at aspeed ciosei ap proximating synchronism, such motor opera ing constantlyat substantially full speed with the vehicle at rest or traveling at anyspeed.

In operating the vehicle the apparatus of also be employed to check andstop the vohiole without modifying the speed of the vchiole-motor.

Reference may be had to my copending ap plication. v

Themotor mechanism in may also be employed when operating fluid is properlydirected therethrough to bring the armature of the vehicleanotor y tospeed, whereupon the said armature may be cut' into circuit, it beingassumed that the vehicle is braked. The supplemental mechanism 2 isemployed to act as a retarding or accelerating engine and does not actas a clutching-engine for uniting the armature of the electric motorwith the driving-axle of the vehicle. This engine 2 when operating hasits frame preferably clutched in engagement with the stationary field ofthe electric motor flexibly at-- tached to the truck-frame at y,whereupon by the proper control of actuating fluid admitted to the saidengine the same will be op erated in one direction to cooperate with thevehicle traction-motor in propelling the vet hicle, or the said enginemay form a retarding means in'checking the speed of the vehi' cle, thisengine 2 thus ordinarily acting as the sole means for braking thevehicle, the pistons thereof performing this function preferably bycompressing the air or fluid in a suitable reservoir until the vehicleis stopped, whereupon the valves to the ports of the engine z areclosed. The engine 2 thus acts to accumulate mechanical energy,preferably in the form of compressed air, which may be used,as will bemore fully hereinafter setforth.

The engines :1; and are each provided with reservoirs t u and t a, whichare preferably fixed with relation to the supporting-framesotherconditions of operation to be hereinafter set forth the auxiliary air orfluid engines are adapted to jelfect the'storage of air under pressurein one or the other of the-reservoirs tuand 6'44, and the air underpressure in these reservoirs may be used in actuation of thevehicle-operating mechanism. The pistons may when required serve to pumpair from one reservoir to its companion reservoir through thecommunicating valves r s r a, as hereinafter setforth.

In Figs. 5 to 11 1 have disclosed the preferred form of valve mechanismand control ling mean that may be employed for effecting the operationof mechanism illustrated in Figs.

2 and 4. The valve-cylinder A contains a three-story ported valve B,ground to fit the interior of the cylinder. The valve-cylinder isprovided with an exhaust-port G and a connection D, ailordingcommunication between the valve mechanism and the reservoir E. Pipes orducts F, G, and H afford communication between the accumulator ofenergyE and the different ports of the engines 01 and .2, the pipes Fand G having communication, respectively, with the right and left endsof the bore h in thedriving-axle, as shown more clearly in Fig. 4, whilethe pipe H communicates with the passage 74'. leading to said bore if inthe driving-axle, as indicated in Fig. 2. I have indicated a switch Kfor closing current through the clutch-coil 0 when the valve mechanismis in proper position to have the engines .2 held from revolving. Ipreferably employ controllers for governing the operation of the valve Bof the form illustrated in Figs. 9 and 10, two such controllers J beingdiagrammatically indicated in Fig. 11, and one of the controllers beingindicated in section and plan in Figs. 9 and 10. A shaft J is inseparable engagement with the handle of the controller, the handle beingprovided with an extension J ,which when the handle registers with thepoint 0 is in line with aslot in the cap-plate or indicating-dial J ofthe control lei, whereupon the handle may be readily removed. Horizontalshafts J are engaged with vertical sha ts J through' mitei gears 3 asindicated in the upper portion of Fig. 5. As indicated in Fig. 5 and inFigs. 6, 7, and 8, the pressure-port L, the reliefport M, and theexhaustport N are formed in and extend lengthwise through the valve Band are so relatively arranged as to present the proper port at theproper time to the corresponding openings orpassageways C, I), F, (fir,and H, extending through the valve -cylinder to effect the proper andharmonious control of the engines :1; and with relation to thevehicle-motor y. The indicating-dial of the controller J is preferablyso marked as to indicate the various operative positions of the rotatingvalve. A reliefvalve 0 is so arranged that it will allow pressure topass from port M to the port L if the pressure in the port-passage Mexceeds the pressure in the reservoir E, communicating with the. port Lby the pipe D.

Assuming that the engine 2 has been operated while retarding the motionof the car(indicated in Fig. 11) sufficiently to store a proper amountof reserve mechanical energy in the form of compressed air or fluid inthe reservoir E or that mechanical energy has been otherwise secured inany suitable way,-l will proceed to describe the operation of them)-paratus of my invention. With the handle of the controller J in theposition indicated in N, the remaining valve-ports L and M being closed.With this adjustment of the Valve mechanism no air is supplied to theengines a and .2 from the reservoir E, and no air is pumped from theengines to the said reservoir.

This is the'adjustment of the valve mechanism 1 justments when the caris to be stopped or reversed. Assuming that the vehicle-motor and thevehicle are stationary, in order to start the vehicle-motor the handleof controller J may be turned backward, say, to point 2, whereupon thevalve mechanism-will be adjusted to admit fluid under pressure from thesupplytank E to the connecting-rapes G and H, exhaust being permittedfrom pipe F through the port N and exhaust-pipe N. The pipe H havingcommunication with the ports of both engines wand z and the pipe Ghaving communication directly with the enginesz, the said engines willremain neutral, while the diiferential engines 41' will be operated andwill revolve the gearing e and quill-shaft a, carrying the armatures ofthe vehicle-motors 1 in a forward direction, sufiicient resistance beingoffered to the gearing (Z of the engines .r by the weightof the caritself to enable these engines :1 to start the armatures from a state ofrest. if the weight of the vehicle is not sufficient for this purpose,the wheels thereof may be braked. \Yhen the armatures of the motors arebrought to speed or started, they then may be switched into circuit withtheir source of supply, and thereby maintained at working or synchronousspeed, whereupon the handle of the controller may be again placed to theneutral point, as indicated in Fig. 10, in which position the valvemechanism will be so adjusted as to prevent the auxiliary pneumaticengines from effecting coupling engagement between the vehicle-motorsand the traction axles and wheels. y

1n Fig. &.l have illustrated trolleys connected with the motor-armatureand engaging trolley-conductors located alongv the line of travel. Toreplenish the chamber E with compressed air that has been exhausted inbringing the vehicle-motors to speed, the controller-handle may beregistered with point 1 forward, the vehicle-wheels still being brakedby any suitable means, whereby an adjustment of the valve mechanism willbe effected that will bring the pipe F in communication with therelief-port M and the pipes Gr and H with the exhaust-port N. Theauxiliary engines .1 will thereupon be operated to compress air into thereservoir-chambers 2., the air being drawn in through the ports a fromthe passage 71? and. the exhaust-port N in communication therewith. Whenthe pressure in the reservoir-chambers i exceeds that in the reservoirE, the pop or relief valve 0 will open and ad'- when the ear isstationary and one of the ad-\ controller contra-clockwise toward pointzero l i mit pressure into the tank E. If the brakes upon thetraction-wheels are now released, the slowly start, owing to thecoupling engagement eifected between the vehicle-motors and thetraction-wheels and axles through the agency of the clutch-engines m,the speed of the car accelerating as the pressure in chambers t of theengines :1: increases. 'It will be observed that by moving the handle ofthe the amount of air pumped will be diminished and the pipe F broughtmore into communication with the exhaust-port N and that when the carisin motion the differential engines will allow the car to travel at acorrespondingly slower speed with relation to the running speed of thevehicle-motor. If the controller-handle is placed at point 2 forward,the pipe F will be brought in direct communication with thepressure-port L, and the engines a: will ofi'er a. definite resistanceor retardation to the revolution of the gears 9, whereby the car may bemoved by power transmitted from the gearing 0, rotated by the armaturesof the vehicle-motors to the gearing d through the agency 'of gearing rAs i the controller-handle nears the point 3. forl ward circuit throughthe clutch-coil 0 is comthis circuit when the controller-handle reachesthis position. By the adjustment of the controlling-valve mechanism,effected when the controller-handle is moved to this position, air

or fluid under pressure is admitted to the pipe 1 G, connected with theaccelerating-engines 2, whichare operated at their full power when thecontroller-handle reaches the point 3 forward. The differential enginesa: tend at the same time to force air back into the reservoirchambers zand the pressure-tank E, whereby elastic connections between thetraction- 1 wheels and the vehicle-motors y are effected. l The frames 0of the accelerating-engines 2 are 1 maintained stationary with respectto the field i portions of the vehicle-motors, whereby upon l thereciprocation of the pistons of the engines dthe gearing r of theengines 2 is operated to aid the vehicle-motors in effecting therotation of the traction-wheels through the turni pleted, preferably byswitch K, which closes l in effort exerted b the ears of engines 2 o r bThe accelerating-engines.

After thecontroller-handle has i passed the point 3 forward the switch K is ioperated to open circuit through the clutch- 1 coil 0 to disconnect theframes of engines 2 l from their engagement with the field portions ofthe vehicle-motors. \Vhen the controllerhandle is placed at point a, thepipesF, G, i and H are closed and the air in chambers a a of the enginesa and .2 is pumped into the cham l hers I. t of said engines, therebycausing a vacuum in each of the reservoir-chambers a \Vith thecontrolling-Va lve mechanism in this I 3 site direction. The car has nowbeen brought to full speed and is being driven by the vehicle-motorsthrough the agency of clutching diiferential motors a, which serve toact as ii xible connections between the vehicle-niotors and thetraction-wheels If the vehicleiuotors should need aid in climbinggrades, for example, the controller-handle may be turned to point 3forward, whereupon the engines will cooperate with the vehicle-moters topropel the car. If, on the other hand, the car should be retarded-as,for example, in descending inclines-the controller-handle is turned in aclockwise direction to point 3 backward. By this adjustment of thecontrellingvalve mechanism the operation of the engines will bereversed, the momentum of the car serving to cause the engines 2 to pumppressure into the tank E, the switch K again s" wing to clutch the frame(1% of engines z to iield portions of the vehicle-motors when thecontroller-handle is at point 3 backward. The t liiferential engines a:will now permit their gears g to revolve, so that, practically speaking,vehicle-motors y are disconnected from the car, the speed of the carbeing retarded in proportion to the increasing pressure in the tank Eand the pressure in chamber 2." iii the engines 2, which is exertedunder the pistons It of the engines As long as the car remains in motionand the controller-handle remains at the point 3 backward pressure ormechanical energy is being stored in the pressure-tank E by theoperation of he engines When the car has been nearly stopped, thecontrolling-handle is placed at the point 0, and braking means are thenapplied to prevent the car from starting from a state of rest untildesired. Through the agency of my apparatus 1 am enabled to cause thecar to travel backward, which is fre quently desired for shortdistances, without changing the direction of rotation of the ar maturesof the vehiclemotors, which may be accomplished by the adjustment of thecontra-:lling-valves, effected in placingthecontrolling-handletothepoint 3 backward. Ifit should he desired to causethe car to travel a great distance in the reversedirection, thearmaturcs of the vehicle-motors should cease to rotate, whereupon theymay be started or brought to synehronousor working speed in a reversedirection by the reverse operation of the eontroller-hamlle, the varioussteps in the control of the mechanism previously described as beingeffected by moving the controller-handle forward being now effected bysimilar movements of the controller-handle backward.

on as it tends to reciprocate in the oppo I have illustrated in Fig. 11duplicated controller-handles and cooperating mechanism, so that the carcan be operated from either end. It also practical to have a pluralityof motor cars in a single train operated from any one platform in unisonby any suitable means.

In Fig. 3 I have illustrated another embodiment of'my improvedaccelerating and retarding engine in the form of duplicated fluidmotorsmounted upon the same shaft. Similar parts in the duplicated portions ofthe structure illustrated in Fig. 3 are given letters of referencesimilar to like parts of the engine illustrated in Fig. 4:. Passages forthe ad mis sion and exhaustion of the fluid under pressure areillustrated in the left-hand portion of the structure shown in Fig. 3 asbeing provided in the axle and in a conicalsleeve or bush fixed withrelation to the axle, about which the frame 0, supporting thereciprocating pistons, is adapted to rotate. Ports or passages forsimilar purposes are illustrated in the righthand portion of thestructure shown in Fig. 3 located solely within a second bush fixed withrelation to the shaft and about which the engine isadapted to rotate.The gear d is se curedto the middle portion of the axle, the gears g,engaging the gear (Z, being common to the duplicated structures. Acasting 1/ serves'to unite the frames a of the duplicated engines, as bybolts, and a friction-clutch or brake-band 0 performs the function bfthe magnetic clutch 0 (shown in Fig. 1-) in that it may serve to renderthe frame stationary with respect to the vehicle. The clutch may beoperated in' any suitable way. W hen it is desired to have the engineact as an accelerator, the clutch is applied to maintain the frames c estationary, and air under pressure is supplied to the ports r '2' or a.5, according to the direction of travel of the vehicle,whereby theengine is operated to exert torque upon the axle. If atmospheric air issupplied through the ports 1* w or c a, the engine will pump air, andthereby retard the motion of the car. After the clutch is released theframes 0 e are free to revolve with the axle or driven shaft, thusremoving the frictional wear which would otherwise occur in the surfaceof the conebearings and to the working parts of the interior mechanism.

The structure illustrated in Fig. 3 is particularly designed for useupon a vehicle that may have its motor upon one shaft and the auxiliaryengine mechanism illustrated in this figure upon another shaft. hen theengine mechanism illustrated is to have its frames c c rotated freelyupon the shaft, the brakeband 0" may be released from its frictionalengagement with the casting 1/. When said frames are to remainstationary, the brake should be applied.

The alternating current traction motor (shown more in detail in Fig. 4)has its maximum efficient speed very closely approaching -lent powerconnection between the tractionmotor and the auxiliary engine in placeof the toothed gearing; but I do not wish to be limited to the toothedgearing.

I have illustrated one type of running-gear in the .form of flangedtractionwheels united by driving-axles; ited to this precise form ofrunning-gear, as other forms thereof may be employed without departingfrom the spirit of my invention.

I use the term engine in the claims broadly, in the sense of anydriving-motor.

It will be seen that I have provided an engine or motor that isstructurally distinct from the prime mover--inthis instance thetraction-motor on the vehicle-and the load operated by the primemover-in this instance the vehicle. There is thus, aside from thetraction system, provided a power-transmis' sion mechanism.

I have shown and particularly described fluid-engines for performing thevarious functions herein set forth; but it is obvious that otherstructures and tures may be employed, and I. do not, therefore, wish tobe limited to the precise arrange- I ment and construction of theapparatus of my invention disclosed. Many features herein disclosed Ibelieve to be broadly new with me irrespective of the preciseconstruction and arrangement illustrated, and I therefore desire toclaim such features broadly irrespective of the preciseinstrumentalities employed.

I have disclosed a single-phase alternatingcurrent motor having onemember fixed upon the vehicle-body and the other member rotatable withrespect to the vehicle-body that is, one member is rotatable withrespect to a point in space and the other member is substantially fixedwith respect to said point, assuming the vehicle to be at a standstill.I do not wish to be limited to a construction, hoy ever, wherein onlyone memberof the motor .is rotatable with respect toa point in space. Itwill be seen that I have provided a novel vehicle construction whereinthere are employed two motors for operating the runninggear, thesemotors and the running-gear be ing in tandem operatively--that is, oneof these elements occurs after the other in operative relation-one ofthe motors serving by variation in its speed to regulate the effect ofthe other motor upon the running-gear. In

the system herein disclosed there is employed a single-phase motorhaving practically a con' stant speed between its members, which n otoris oined. to the running-gear by means of a second motor in a mannerthat has been arrangement of strucv avelncle, ot avehrcle-motor forpropelling the or union with the but I do not wish to be lim- 1 l l lfully described. I do not wish to be limited, however, to the locationof the motors in the relative orderset forth. It will be seen that onemotor has a mounting that is substan tially fixed with relation to thevehicle body or truck, which motor in the embodiment of the inventionset forth is a single-phase motor, the other motor rotatably mountedwith respect to the vehicle body or truck and has one of its membersadapted for engagement rotatable element of the aforesaid motor and hasthe other of its members adapted for engagement or union with therotating element of the running-gear.

In the drawings 1 have illustrated a singlemotor circuit for supplying asingle-phase current to the single-phase motor. I do not wish to belimited, however, to the use of only one single-phase circuit extendingalong the line oftravel, for it is obvious that a generator 'may beemployed for supplying the singlephase circuit in operative associationwith the vehicle, which source of single-phase current may form apart ofthe complete apparatus that may-generate current or currents in additionto that supplied to the single-phase cir- 'cuit'.

Having thus described my invention, I claim as new and desire to secureby Letters Patent" I.
